Report due January 7 for FOURTH REPORTING PERIODOctober through December

It is the responsibility of the Industrial User to schedule sampling In advance ofthe reportingdates to allow for sample analysis and submittal of the Periodic Compliance Report by theJanuary 7. April 7, July 7, and October 7 dates. Sampling and reporting requirements shall bein effect for the duration of the existence of tde regulated proccss(cs).

In the event sampling performed by the Industrial User indicates a violation ofa dollymaximum or average limit, the Industrial User shall notify the WSSC of the evioltionwithin 24-hours of becoming aware of the violation. Within 5 days of the notifiction tothe WSSC, the Industrial User shall submit a copy of the analytical data associated withthe violation, a copy or the chain of custody, and an original certification statement. TheIndustrial User shall repeat the sampling and analysis of the parameter in violation, andsubmit the results or the analysis, a copy of the chain of custody, and an originalcertification statement to the WSSC within 30 days of becoming aware of the violation.The Industrial User may not substitute scheduled self-monitorlig in place of resamplingfor a violation.

If the violation is questionable, report the violation within the requited 24-hour period.Reporting of violations may not be delayed during an investigation into the sampling datavalidity. In the event that the WSSC invalidtes an Indusrial User's sampling data, theIndustrial User shall resample each invalidated parameter for the number of days invalidated.

ill. DEFINITION OF TERMS

Calibration - The adjustment of pF equipment at the onset of monitoring by using buffersolutions to determine deviations.

Composite sample - A combination of individual samples collected at regular intervals over atime period not to exceed 24 hours in any given calendar day. The volumne of each individualsample my be either proportional to the flow rate during dte sample period (flow composite), orconstant and collected at equal imec intervals during the composite period (time composite).Composite sampling shall be representative ofthe process wastcstream for that day.

Consistent eompliance - Compliance with all applicable pretreatment standardsjmd reportingrequirements during a reporting period.

Continuous pH monitoring - A pti reading taken automatically at a frequency of at leastonce/minute. In the event that an Industrial User montous its pH continuously, a pH violationshall be construd as ny excursion less than 6.0 or greater than 10.0 for more than 15 minutes atany one time, or more than 30 minutes in aggregate, for any calendar day. The p11 shall not be lessthan 5.0 for any period of time.

Daily maximum - The maximum allowable discharge concentration of a pollutant in awastestreamn during a calndar day.

Estimated flow - A calculated volume or discharge rate which is based on a technical evaluationof the sources contributing to the discharge including, but not limited to, pump capabilities, watermeters, and batch discharge volumes.

Field Check - A check on pH equipment at the end of a monitoring day using buffer solutions. 1No

adjusunment is made to equipment.

Four-day average - The arithmetic average of daily values for four consecutive monitoring days.

Grab sample - An individual sample collected over a time period not exceeding 15 minutes,without regard for flow or time. In the event that an Industrial User monitors its pH by collectinggrab sampics, a violation shall exist ifgreater than 6.25% of the grabs taken that day are less than6.0 or greater than 10.0, or If any of the grabs taken arm less than 5.0.

Measured flow - Flow obtained from appropriate flow measurement devices and methodsconsistent with scientific practices to ensure accuracy and reliability. Such devices shall bemaintained to ensure thint the accuracy of the measurements is consistcnt with the acceptedcapability of that type of device. Devices selected shall be capabie of measuring flows with amaximum deviation of less than 10% for true discharge rates throughout the range of xpecteddischarge volumes.

Monthly average - The arithmetic average of the values for effluent samples collected over acalendar month.

20

POTW - A Publicly Ovued Treatment Works, which includes any device and system used instorage, treatment, recycling, and reclamation ofmunieipal sewage or industrial waste era liquidnatume Also included are scwers, pipes. mnd other conveyances only if they convey wastwater toa POWT treatment plant. The term also means the municipality as defrmed in Section S02.(4). ofthe Clean Water Act, which has jurisdiction over the indirect discharges to and the discharges fromsuch a treatment works.

Quarter - For reporting purposes, a quarter shall consist of the months ofJanuay - March,April - June, July - September, and Octobe - December.

Severe Property Damage - Substantial physical damage to property, damage to the treatmentfacilities which causes them to become inoperable, or substantial and pemanent loss of naturalreources which can reasonably be expected to occur in the absence of a bypass. Severe propertydamage does not mean economic loss caused by delays in production.

Total Toxic Organics - The summation of all toxic organic compounus with a concentmtion ofgreatcr than 10 microgtoms/liter. This list consists ofthose compounds appearing in thecategorical standard to which the industry is subject. Noncanegorical Industrial Users shall besubject to the total toxic organics list appearing in 40 CFR 433.11.

Variances in duplicate sample results (excluding pit*) - The following equation will be used todetermine the acceptability of any variances between WVSSC and Industrial User monitoring datacollected on the same day.

21A-Bl x 100 A =WSSC Results(A+B) B = dstry Results

If the results of this calculation exceed 20%, the variance between the remlts is unacceptable andthe Industrial User's monitoring data will not be used.

*14 the event that the Industrial User and the WSSC monitor for pH on the same day. the WSSCsdata %ill be used to detecmine compliance.
